Army doesn't allow them either. Only females.

Was that the regulation that was in place when the photo that you posted was taken? Uniforms and the regulations that govern them have changed drastically over the past 20 years. But like I said, if a former president did ask a Soldier to break a regulation, then it was a mistake. The fact that it has taken you this long to find a photo and find the current Army regulation governing Soldiers holding umbrellas while in uniform is pretty strong evidence that it has not been a common practice.
